Question
Considering the case of a parallel plate capacitor being charged, show how one is required to generalize Ampere’s circuital law to include the term due to displacement current.
Solution
Ampere’s circuital law states that,
Electric flux across a parallel capacitor is given by, 
Current in the plates of the capacitor is given by, 
This is the missing term in the ampere's law.
Therefore, total current in the conductor is the sum of displacement current and conduction current.
